Obtaining nanocarbon using the electric-discharge treatment method of organic liquids

Abstract

The principal possibility of nanosize carbon-material synthesis in macroamounts for short intervals of time using the method of electric explosion in a liquid is shown. Conformities with the law of obtaining nanocarbon upon many-cycle treatment are explored; these demonstrated a swaying, falling practically to zero, character of an increasing material mass with an increase in the cycles. The mass of the obtained nanocarbon is determined by the amount of atoms in the chains of the hydrocarbons, by the injected energy in a plasma channel during one pulse, and the quantity of treatment cycles.

Nanosecond-pulsed spark discharge plasma in liquid nitrogen: synthesis of polynitrogen from NaN3

“…Electrical discharges in liquid have been used extensively for generation of nanostructured materials (see, for example, [1][2][3]). Nanosecond-pulsed spark discharges in liquids, including liquid nitrogen, have been also shown to be more reproducible with increased repeatability of produced materials [4,5].…”

Synthesis of two-dimensional lead sheets by spark discharge in liquid nitrogen

“…Electrical parameters also greatly affect the way electrodes are eroded and they modify the chemical processes in the plasma. At least, two main categories of electrical discharges can be defined: high current -low voltage (~100 A, 30 V) (Sano 2004) and high current -high voltage (~100 A, 10 kV) (Kuskova et al 2007). Plasma ignition is only possible in the former category if electrodes are put in contact.…”
